After notification received PL/SQL Call back doesn't trigger
Hello,
In our recent Oracle 12.0.2.0, we have implemented the advanced queuing asynchronous notification feature, as it is explained here : Doc ID 235397.1
It works but sometimes it fails without any code change.
Here is the process :
A Message is well enqueued into the queue table. Then we checked if the notification is carried out by querying V$EMON vue, this step works fine but the message is still in the queue table with status 0 (READY).
We have chacked DBA_SUBSCR_REGISTRATIONS to confirm that the PLSQL procedure is set correctly, it is.
Is anyone know where to look to find what's wrong ?
